METHOD or MAKING coMB-cnsns.

Application led August 30, 1918.

To allai/1,0m t may concern:

Be it known that I, ARTHUR H. FRANHE, a citizen of the United States, and resident of Manitowoc, in the county of Manitowoc and State of Wisconsin, have invented certain new and useful Improvements in Methods of Making Comb-Cases; and I do vhereby declare that the following is a full,

clear, and exact description thereof.

My invention relates to new and useful improvements in comb cases and other simi.- lar flat receptacles of that type formed of a body sheet of material bent to provide the receptacle, and having a cover sheet disposed thereabout to lend a nished appearance to the article, the body sheet being usually of comparatively coarse material to lend sufficient strength to the article at a minimum cost. My invention further contemplates an improved method for forming comb cases and other similarly shaped articles having covered body members.

It is in general the object of my invention to simplify the structureof articles of this character, and to improve the appearance and durability of such articles without departing from a minimum cost of manufacture.

j A'furtherobject resides in the provision of a method of forming such articles wherein a most compact and neat article may be procured with a minimum number of manufacturing steps.

With these and other objects and advantages in view, which will be apparent as the description proceeds, my invention resides in the novel features of construction, combination and arrangement of parts, as hereinafter described and defined by the appended claims, it being understood that changes in the precise embodiment might be made by those skilled in the art without departing from the spirit of the invention.

In the accompanying drawings:

Fig. 6 is a perspective view of the com'- pleted article.

Referring now more particularly to the accompanying drawings, the first step in forming my improved receptacle consists in feeding a continuous flattened tube of body material 5 onto a iat strip 6 of cover material, the tube engaging the cover strip longitudinally thereof and adjacent one side edge of the strip. The body tube is formed of a heavier and coarser strip of material which is previously folded 'in any suitable and preferably conventional manner to dispose its side edge portions in lapped relation, and in the present arrangement the width of the side edge portions is but slightly less than the width of the intermediate portion, thus forming a double wall for one side of the tube. The entire faces of the body strip andl cover strip which are opposed carry coatings of paste, and thus when the body strip Yis folded, its side portions are pasted together. j The space between the body strip and the adjacent sidehof the cover strip is suflicient to form a valance flap 7, and after the folded body strip has been fed onto the cover strip, this flap portion 7 of the cover strip is folded about the adjacent edge portion of the receptacle tube to cover the same. V

The strips, thus connected are then cut in suitable lengths on lines 8 and 9 disposed in offset relation and connected by 'a cut line 10 disposed immediatelyy outwardly of the inner side of the body tube, with respect v toits position on thecover strip.

By cutting in this' manner, as shown in Fig. 2, one vend of the free expanse of the cover strip is projected past the adjacent end of the body tube and its connected cover strip portions. Y

The nextstep in the formation of the article is to bend its free expanse 11 of cover strip about the exposed side of the body tube, the width ofthe free expanse being sufficient to lap the flap 7.

The projected end portion of the free expansell, which then forms a projecting flap 12 on the article, is next bent about the end of the body tube. Thus the sides and edges and one end of the receptacle are covered in a Vinished manner, as shown in Fig. 4, and the final ste in forming the finished article is to cut o the other end inwardly of the edge of the cover side 11, this cut being preferably concaved at its intermediate portion Patented Mar. 25, 1919.

ving a considerably to provide nger spaces in the ends of the receptacle Walls.

An exceedingly simple, durable and Yat tract-ive receptacle of the present nature may thus be provided with a minimum number of manufacturing steps and in a most ready manner permitting an exceedingly low cost of manufacture as compared tothe methods now employed in manufacturing articles of this character.

One of thel methods followed in making such articles is to `provide separate dies and consequently separate cutting operations for the body sheet and cover sheets, thus `requirgreater amount of labor in cutting fthe sheets and. in folding the sh'eets together, than is involved in my improved method. Another method heretofore employed in forming such articles is to cut the connectedcover and body sheets from continuous strips on straight parallel lines and subsequently cutting away a part of the body sheet and a portion of the adjacent end of the cover sheet to provide a flap corresponding to my'end flap 12. This method also involves a considerablylgreater amount of labor, and an obvious wastage of material. In both methods, andparticularly in the latter method, it is` in practice found impossible to procure an exact uni form size of the articles and it is a decided disadvantage particularly when it is desired to print upon the articles.

In carrying out my invention continuous` strips of body and cover material are cut fromthe usual commercial rolls and l thus avoid the Wastage incidental to cutting separate sheets from the roll without adding to the cost `of cutting, it being particularly noted that in carrying out my method Iam enabled to use a single set of dies for all diderent desired widths and lengths of the nished articles.

Vhat is claimed is:

l. That method `of forming an article of the class described, which consists in feeding continuous length of fiattened body material onto a continuous `strip of cover.

material, in simultaneously cutting lengths fromsaid cover stripy and body material transversely with a `portion of oney end "of the .severed length of cover strip extending past the adjacent end of the severed length of body material, and in then folding the free portions of the cover strip around the adjacent edge portions of the body ma terial.

:2. That method of forming an article of the class described, which consists in feed ing a continuous length of flattened body material onto a continuous strip of cover material, in simultaneously cutting lengths from said cover strip and body material transversely with a portion of one end "of the severed lengths of cover strip extending past the adjacent end of the severed length of body material, in then folding the free portions of the cover strip around'the adjacent edge portions of thebody material, and in cutting ofi' the other ends of the tube and cover strip.`

3. That method vof forming an article of i the class described, which consistsin feeding a continuous length of flattened Abody material longitudinally onto a continuous strip of cover material at one side portion thereof, in severinglengths from said cover strip and body material on offset transverse cut lines connected by a longitudinal cut line in the cover strip adjacent the inner Iedge of the body material whereby a portion of one end of the cover strip length extends past the adjacent end of the body material length, and in then folding the free portions of the cover strip around the adjacentedges of the body material.:

4. That method of the class described which consists in feeding formingan article of e a continuous length of flattened body maand in then foldingthe free portions lof the cover strip around the adjacent edges of the body material.

In testimony that l have hereunto set my hand at Manitowoc, in the county of Manitowoc and'State of llisconsin. Y
